Just heard over the weekend that the board has agreed to open up the journal, so I've taken the necessary steps to do that. This post explains how we were locking down the system; I started by changing the ialltjournal.xml file on the server so that it was set to allow="*". Then we restarted Tomcat, but it didn't work; nothing was accessible. So in the end I just deleted the file on the server, which achieved the desired result. We're still working out the details of how the ialltjournal.org site will interact with the lettuce site.
